Atrial septal defect with atrial fibrillation treated by one-stop radiofrequency ablation and transthoracic closure under total endoscopy: A case report / 中国胸心血管外科临床杂志

@#Surgical treatment of atrial septal defect (ASD) mainly includes occlusion or repair under cardiopulmonary bypass. Surgical treatment of atrial fibrillation includes transcatheter radiofrequency ablation or Maze surgery under cardiopulmonary bypass. There are many treatments for ASD patients combined with atrial fibrillation, but each has its own advantages and disadvantages. We reported an ASD patient combined with atrial fibrillation treated by totally endoscopic "one-stop" radiofrequency ablation and simultaneous transthoracic ASD occlusion of atrial fibrillation, with good postoperative results.

Effects of optimized catheter clipping training and automatic balloon retraction ureteral catheter removal on first urination of patients after neurosurgery / 中国实用护理杂志

Objective:To investigate the effect of optimized catheter clipping training and automatic balloon retraction ureteral catheter removal on first urination of patients after neurosurgery, and provide guidance for postoperative micturition of these patients.Methods:From August 2020 to August 2021, 208 patients admitted to Department of Neurosurgery, the Affiliated Hospital of Xuzhou Medical University, undergoing craniocerebral surgery under general anesthesia and indurating catheter were selected as the study subjects by convenient sampling. They were divided into control group ( n=69), observation group A ( n=69) and observation group B( n=70) by random number table method. The control group received routine catheter clipping training and routine ureteral catheter removal, the observation group A received optimized catheter clipping training and routine ureteral catheter removal, and the observation group B received optimized catheter clipping training and automatic balloon retraction ureteral catheter removal. The first micturition time, first micturition volume, micturition circumstance, pain score and urethral irritation sign of the three groups were observed and compared. Results:The first urination time in observation group A and B were (11.58 ± 6.59) min and (10.06 ± 5.91) min, respectively, lower than (37.14 ± 13.74) min in control group, and the difference was statistically significant ( t=13.94, 15.07, both P<0.05); there was no significant difference between observation group B and observation group A ( P>0.05). The first urine volume were (303.66 ± 43.74) ml in control group, (299.06 ± 41.26) ml in observation group A and (299.28 ± 43.17) ml in observation group B, and the difference was not statistically significant ( P>0.05). The incidence of urination (spontaneous urination, induced urination and urinary retention) in observation group A was better than control group ( χ2=16.47), while observation group B was better than observation group A and control group ( χ2=8.59, 37.83), the differences were statistically significant (all P<0.05). There was no significant difference in pain score of ureteral catheter removal between observation group A (2.71 ± 0.67) and control group (2.87 ± 0.78) ( P>0.05). The score of observation group B (1.41 ± 0.65) was lower than that of control group and observation group A, the differences were statistically significant ( t=11.93, 11.62, both P<0.05). There was no significant difference of the incidence of urethral irritation (grade 0, 1, 2, and 3) between observation group A and control group ( P>0.05). Observation group B was lower than control group and observation group A, the differences were statistically significant ( t=38.81, 25.27, both P<0.05). Conclusions:Optimized catheter clipping training and automatic balloon retraction ureteral catheter removal can effectively shorten the first urination time of patients after neurosurgery, reduce the pain of ureteral catheter removal and urethral irritation during the first urination, improve the success rate of the first urination, and effectively prevent the occurrence of urinary retention.

Neuroendoscopy in microsurgical clipping for ruptured posterior communicating artery aneurysms via keyhole approaches / 中华显微外科杂志

Objective:To explore the value of application and manipulation technique of neuroendoscope in microsurgical clipping of ruptured posterior communicating artery(PCoA)aneurysms via keyhole approaches.Methods:From January 2018 to December 2020, the clinical data of 52 patients who received microsurgical clipping for ruptured via keyhole approach were retrospectively analysed. Forty-one patients had the intraoperative endoscopic monitoring. The supraorbital keyhole approach or pterional keyhole approach was applied based on the characteristics of the aneurysms. According to the in-surgery requirement, a 30° rigid neuroendoscope was used before and/or after clipping. All patients entered postoperative follow-up in outpatient clinic and were evaluated with the modified Rankin Scale(mRS).Results:All 52 patients had 52 ruptured PCoA aneurysms. Eighteen of the patients were treated via supraorbital keyhole approach and 34 via pterion keyhole approach. Pre-and post-clipping endoscopic observation were carried out in 12 cases and 29 only with post-clipping endoscopic observation. Residual aneurysmal neck was detected in 3 patients. Missed clipping of perforators was found in 2 patients and followed by proper adjustment of clips. All patients received follow-up angiographic examinations. Total obliteration of the aneurysm and an intact of internal carotid artery and PCoA were found in 41 patients by the intraoperative endoscopic observation. Two residual aneurysmal neck were detected in 11 patients without intraoperative endoscopic observation. After 11 to 45 months of follow-up, all patients had good recovery(mRS 0-1).Conclusion:It is a safe and effective method with endoscopic observation during microsurgical clipping procedure for ruptured PCoA aneurysms via keyhole approaches. It can effectively make up for the insufficient visual angle of microscope, realise the anatomical relationship between the aneurysm and adjacent structures, and avoid residual aneurysmal neck and an iatrogenic injury to the parent artery and perforators.

"One-stop" left atrial appendage clipping combined with transcatheter aortic valve replacement for patients with atrial fibrillation and aortic valve disease / 中国胸心血管外科临床杂志

@#Objective    To summarize the experience and efficacy of "one-stop" left atrial appendage clipping (LAAC) combined with transcatheter aortic valve replacement (TAVR) for patients with atrial fibrillation (AF) and aortic valve disease. Methods     From April 2018 to March 2021, 16 patients with AF and severe aortic valve disease underwent "one-stop" LAAC and TAVR in our department. All patients had long-standing persistent AF. There were 10 males and 6 females with an average age of 77.2±6.2 years. CHA2DS2-VASc score was 4.4±0.8 points, and HAS-BLED score was 3.5±0.7 points. Results    All patients successfully underwent "one-stop" LAAC combined with TAVR. There was no death during perioperative and follow-up periods. The length of the left atrial appendage base measured during the operation was 37.8±3.5 mm. The types of atrial appendage clip were 35 mm (n=3), 40 mm (n=8) and 45 mm (n=5). The time required for clipping the left atrial appendage (from skin cutting to skin suturing) was 25.7±3.8 min. There was no stroke or bleeding of important organs during the perioperative period. The average hospital stay was 6.8±2.0 d. The follow-up time was 19.6±10.1 months, during which there was no patient of cerebral hemorrhage or cerebral infarction. During the administration of warfarin, 2 patients had subcutaneous ecchymosis and 1 patient had gingival bleeding. Conclusion    "One-stop" LAAC combined with TAVR can be safely and effectively used to treat AF and aortic valve disease patients with high risk of thromboembolism and anticoagulant bleeding. The early and middle-term curative effect is satisfactory.

Aneurisma trombosado de arteria comunicante anterior asociado a síntomas visuales / Thrombosed anterior communicating artery aneurysm associated with visual symptoms

Introducción: Los aneurismas de la arteria comunicante anterior (AComA) se presentan frecuentemente como causa de hemorragia subaracnoidea espontánea (HSAE), en casos raros se asocian a síntomas visuales por compresión mecánica o ruptura y su tratamiento quirúrgico a menudo representa un desafío. Descripción del caso: Se presenta el caso clínico de una paciente adulta con disminución de la agudeza visual del ojo derecho a predominio temporal, y hallazgos en RMN cerebral y angiografía compatibles con un aneurisma grande de AcomA, asociado a trombosis parcial; se realizó clipaje y trombectomía del aneurisma, la panangiografia de control evidenció exclusión completa de la lesión con posterior resolución del déficit visual. Discusión: El déficit visual por un aneurisma de la AcoA se puede generar por varios mecanismos, uno de ellos es la ruptura del aneurisma hacia el nervio óptico, con la subsecuente formación de un hematoma, adherencias y fibrosis; el otro mecanismo es la compresión mecánica de un aneurisma gigante no roto. El manejo quirúrgico a menudo implica técnicas complejas microquirúrgicas para intentar resolver el efecto de masa y excluir el aneurisma. La terapia endovascular es otra alternativa de tratamiento, pero tiene desventajas respecto a la cirugía. Conclusión: Los aneurismas de la AComA en raros casos se pueden asociar a síntomas visuales, debido a que por lo general se romepen cuando son pequeños, y no alcanzan a tener el tamaño suficiente para generar compresión de la vía óptica. Las técnicas microquirúrgicas ofrecen un método efectivo para disminuir el efecto de masa y mejorar los síntomas visuales

Introduction: Aneurysms of the anterior communicating artery (AComA) frequently present as a cause of spontaneous subarachnoid hemorrhage (HSAE), in rare cases they are associated with visual symptoms due to mechanical compression or rupture and their surgical treatment often represents a challenge. Description of the case: We present the clinical case of an adult patient with a decrease in visual acuity due to the right eye with a temporal predominance and findings on brain MRI and angiography compatible with a large AcomA aneurysm associated with partial thrombosis; clipping and thrombectomy of the aneurysm were performed, the control panangiography showed complete exclusion of the lesion. With subsequent resolution of the visual deficit. Discussion: The visual deficit due to an AcoA aneurysm can be generated by several mechanisms, one of them is the rupture of the aneurysm towards the optic nerve, with the subsequent formation of a hematoma, adhesions and fibrosis; The other mechanism is mechanical compression of a giant, unruptured aneurysm. Surgical management often involves complex microsurgical techniques to try to resolve the mass effect and exclude the aneurysm. Endovascular therapy is another treatment alternative, but it has disadvantages compared to surgery. Conclusion: AComA aneurysms in rare cases can be associated with visual symptoms, because they generally rupture when they are small, and are not large enough to generate compression of the optic pathway. Microsurgical techniques offer an effective method to alleviate the mass effect and improve visual symptoms

Is there neural and functional recovery after clip removal in cervical experimental sympathectomy? / Existe recuperação neural e funcional após a retirada de clipe quando da indução de simpatectomia cervical experimental?

ABSTRACT Background: The surgical treatment of hyperhidrosis by thoracic sympathectomy has brought, in addition to symptomatic relief for many, its main adverse effect: compensatory or reflex sweating. The clipping technique in place of the sympathetic nerve section gave rise to the hope of reversibility, but the positive results showed to be quite divergent, evidencing the academic deficiency regarding the study of this phenomenon. Aim: To observe micro and macroscopic damage caused by the polymer clip on sympathetic nerve of rabbits seven days after their clipping and the findings after three weeks of clip removal. Method: In this experimental study, 20 rabbits were divided into two groups of 10, group 1 (clipping) and group 2 (de-clipping). The right cervical sympathetic nerve of all animals was clamped with polymeric clip, and in group 2 the nerve was unclipped seven days later. Group 1 rabbits were induced to death on the 7th postoperative day, and group 2 on the 21st after removal of the polymer clip. Macroscopic variables were: clip appearance, presence of discontinuity lesion, infection and adhesions around the nerve. H&E was used in the evaluation of the phases and degree of the inflammatory process and presence of necrosis, and picrosirius red F3BA for quantification of collagen. Results: The cervical sympathetic nerve was intact, without necrosis or infection in all animals of the experiment; there were adhesions in both groups, being minimal in eight animals of each group and moderate or intense in two; the clip was completely closed in all animals at the 7th postoperative day; the inflammatory process shown was chronic, with monomorphonuclear predominance. There was no significant difference between groups regarding the intensity the inflammatory process, but the amount of collagen type I and type III was significantly higher in group 2. Conclusions: The injury caused by the polymer clip on the sympathetic nerve may be reversible, allowing functional return in the areas involved in the simulated cervical sympathectomy. Clipping of the cervical sympathetic nerve using a polymer clip does not cause discontinuity injury.

RESUMO Racional: O tratamento cirúrgico da hiperidrose pela simpatectomia torácica trouxe além do alívio sintomático para muitos, também seu principal efeito adverso: o suor compensatório ou reflexo. A técnica de clipagem do nervo simpático no lugar de sua secção deu margem à esperança de reversão do procedimento; porém, os resultados mostram-se bastante divergentes e pouco conclusivos Objetivo: Observar a lesão provocada pelo clipe de polímero em nervo simpático de coelhos sete dias após sua clipagem, comparando-a com os achados após três semanas da retirada do clipe. Método: Estudo experimental, com amostra formada por 20 coelhos, divididos em dois grupos de 10, sendo o grupo 1 chamado clipagem e o 2, desclipagem. Todos foram submetidos à clipagem do nervo simpático cervical direito com clipe polimérico, e no grupo 2 realizou-se a desclipagem sete dias após. Os coelhos do grupo 1 foram submetidos à eutanásia no 7º dia de pós-operatório, e os do grupo 2 no 21º dia após a remoção do clipe. Observou-se na macroscopia o aspecto do clipe, a presença de lesão de descontinuidade, infecção e aderências ao redor do nervo. Para estudo microscópico utilizou-se a coloração H&E na avaliação das fases, grau do processo inflamatório e presença de necrose, e a de picrosirius red F3BA para quantificação de colágeno. Resultados: O nervo simpático cervical foi identificado íntegro, sem necrose ou infecção em todos os animais do experimento; havia aderências em ambos os grupos, sendo mínimas em oito de cada grupo e moderadas ou intensas em dois; em toda a amostra o clipe encontrava-se completamente fechado no 7º dia de pós-operatório; o processo inflamatório presente foi do tipo crônico, com predomínio monomorfonuclear, não se observando diferença significativa em relação ao grau do processo inflamatório entre os grupos; porém, a quantidade de colágeno tanto do tipo I quanto do tipo III foi significativamente maior no grupo 2. Conclusões: A lesão provocada pelo clipe de polímero em nervo simpático pode ser reversível possibilitando o retorno funcional nas áreas envolvidas na simpatectomia cervical simulada. A clipagem do nervo simpático cervical com uso de clipe de polímero não causa lesão de descontinuidade.

Terapia endoscópica combinada en hemorragia diverticular de colon / Combined endoscopic therapy for colonic diverticular bleeding

La hemorragia diverticular es la causa más frecuente de hemorragia digestiva baja. La hemorragia es abrupta, indolora, abundante. La mayoría de los divertículos que sangran se localizan en el lado derecho, este sangrado se autolimita hasta en un 80% de los casos. Cuando no se autolimita su manejo puede llegar a ser complejo. El manejo de estos sangrados, pueden variar desde conservador, endoscópico, arteriografía más embolización y el quirúrgico. Entre las alternativas de manejo endoscópico, tenemos la terapia de inyección, la térmica, hemoclips, ligadura con banda. El presente caso es de un paciente con hemorragia diverticular en el que se realizó terapia endoscopica combinada, infiltración de adrenalina, aplicación indirecta de hemoclips y aplicación tópica de ácido tranexámico que es un antifibrinolítico.

Diverticular bleeding is the most common cause of lower GI bleeding. The bleeding is most often abrupt, painless and abundant. Most of the bleeding diverticula are located on the right side of the colon, this bleeding is self-limited in up to 80% of cases. When it is not, it could turn into a difficult situation to manage. The management of these bleeds can vary from conservative to an endoscopic, arteriography plus embolization and surgical. Among the endoscopic management alternatives, we have injection therapy, thermal therapy, hemoclips, band ligation. The present case is about a patient with diverticular bleeding who underwent combined endoscopic therapy, adrenaline infiltration, indirect application of hemoclips, and topical application of tranexamic acid, which is an antifibrinolytic.

Ultra-Early Versus Early Aneurysm Surgery After Subarachnoid Hemorrhage: A Retrospective Outcome Analysis

Object The timing of definitive management of ruptured intracranial aneurysms has been the subject of considerable debate, although the benefits of early surgery (until 72 hours postictus) are widely accepted. The aim of the present study is to evaluate the potential benefit of ultra-early surgery (until 24 hours) when compared with early surgery, in those patients who were treated by surgical clipping at the Neurosurgery Department of the Coimbra Hospital and University Centre. Methods A 17-year database of consecutive ruptured and surgically treated intracranial aneurysms was analyzed. Outcome was measured by the Glasgow Outcome Scale (GOS). Baseline characteristics were analyzed by the Fisher exact test, the chi-squared and Mann-Whitney tests. Logistic regression was used to assess the impact of good grade according to the World Federation of Neurological Surgeons (WFNS) scale and ultra-early surgery in a good GOS outcome. Results 343 patients who were submitted to surgical clipping in the first 72 hours postictus were included, 165 of whom have undergone ultra-early surgery. Demographics and preoperative characteristics of ultra-early and early surgery patients were similar. Goodgrade patients according to the WFNS scale submitted to ultra-early surgery demonstrated an improvedGOS at discharge and at 6months. Poor-grade patients according to theWFNS scale submitted to ultra-early surgery demonstrated an improved GOS at discharge. Conclusions Ultra-early surgery for aneurysmal subarachnoid hemorrhage patients improves outcome mainly on good-grade patients. Efforts should be made on the logistics of emergency departments to consider achieving treatment on this timeframe as a standard of care.

Aneurisma gigante de Arteria Cerebral Media: Trapping y By-Pass / Giant Aneurysm of the Middle Cerebral Artery: Trapping and By-Pass

Objetivo: Presentar la resolución quirúrgica de un aneurisma gigante de arteria cerebral media mediante técnica de Trapping y By-Pass. Introducción: La tasa de mortalidad a 5 años de pacientes con aneurismas gigantes es del 80%. Debido a su cuello ancho en ocasiones el clipado directo no es posible, requiriendo realizar Trapping del aneurisma seguido de revascularización mediante By-Pass. Material y Método: Se analizaron datos de historia clínica, imágenes complementarias pre y postquirúrgicas, así como imágenes de video intraoperatorias de un paciente portador de aneurisma gigante de arteria cerebral media intervenido en nuestro centro. Resultados: Mediante abordaje Pterional se localizó arteria temporal superficial y sus ramos. Luego de una cuidadosa disección del saco aneurismático se intentó el clipado primario, debido a su cuello ancho, aterosclerosis asociada y trombo intrasacular, el flujo en la rama temporal de arteria cerebral media era comprometido por el clip. Se decidió la oclusión del aneurisma mediante técnica de trapping y, en mismo tiempo quirúrgico, realización de By Pass extra-intracraneano de arteria temporal superficial a rama temporal de arteria cerebral media. A su vez se secciono el aneurisma y se removió el trombo contenido en su interior, logrando disminuir el efecto de masa ejercido por el mismo. Se corroboro permeabilidad intraquirurgica mediante Doppler y en el postoperatorio alejado mediante angiotomografía con reconstrucción 3D. El paciente evoluciono sin complicaciones asociadas con un Rankin modificado de 1. Conclusión: Se presentó resolución quirúrgica de aneurisma gigante de arteria cerebral media mediante técnica de Trapping seguida de By-Pass extra-intra craneano temporo-silviano

Objective: To present the surgical resolution of a giant aneurysm of the middle cerebral artery using Trapping and By-Pass technique. Introduction: The 5-year mortality rate of patients with giant aneurysms is 80%. Due to its wide neck, sometimes-direct clipping is not possible, requiring trapping of the aneu-rysm followed by bypass revascularization. Material and Method: Clinical history data and intraoperative video images of a pa-tient with a giant aneurysm of the middle cerebral artery were analyzed. Results: The superficial temporal artery and its branches were identified through a Pterional approach. After careful aneurysm dissection, primary clipping was attempted, but the flow in the temporal branch of the middle cerebral artery was compromised. Due to its wide neck, associated atherosclerosis and intrasaccular thrombus, an Extra-intracranial bypass was performed from superficial temporal artery to temporal branch of middle cerebral artery, followed by trapping technique of the aneurysm. Then the aneu-rysm was sectioned and the thrombus contained inside was removed, decreasing the mass effect exerted by it. A Doppler probe was used to corroborate bypass permeability, as well as 3D reconstruction angiotomography during the postoperative period. The pa-tient was discharged without associated complications and a modified Rankin scale of 1. Conclusion: Surgical resolution of a giant middle cerebral artery aneurysm was present-ed by Trapping technique followed by extra-intra-cranial temporo-Silvian bypass

Long-term clinical outcomes of patients with aneurysmal subarachnoid hemorrhage in Yunnan Province / 南方医科大学学报

OBJECTIVE@#To investigate the clinical outcomes of patients with aneurysmal subarachnoid hemorrhage (aSAH) after surgeries in Yunnan Province.@*METHODS@#We retrospectively analyzed the demographic features, vascular risk factors, severity at admission, and aneurysm locations in 85 patients with aSAH receiving surgical interventions in Yunnan Province. All the patients were treated by aneurysm clipping or coiling and followed up for clinical outcomes and recovery of daily activities evaluated by modified Rankin Scale (mRS) and Activities of Daily Living (ADL) scale, respectively.@*RESULTS@#Thirty-four of the patients (40.0%) underwent aneurysm clipping and 51 (60.0%) underwent aneurysm coiling. During a median follow- up period of 66.23 months (IOR, 12.03 months), 84.7% of the patients had low mRS scores, and 78.8% lived independently. The WFNS grade at admission was significantly correlated with the follow-up mRS scores (95%: 1.48-19.09, =0.011) and ADL (95%: 2.55-28.77, 0.05), but the cost of hospitalization was significantly higher in coiling group than in the clipping group ( < 0.001).@*CONCLUSIONS@#Both aging and a high WFNS grade at admission are associated with a poor prognosis of aSAH, for which aneurysm clipping and coiling have similar long- term outcomes, but for patients with a high WFNS score, aneurysm clipping is favored over coiling in terms of health economics.

Comparison of microsurgical clipping and intravascular interventional embolization on nerve function recovery in patients with posterior communicating aneurysm combined with oculomotor paralyses / 中国医师杂志

Objective To compare the influences of microsurgical clipping and intravascular interventional embolization on the nerve function recovery in patients with posterior communicating aneurysm combined with oculomotor paralyses.Methods Eighty-six patients with posterior communicating artery aneurysm accompanied by oculomotor nerve palsy admitted to Qianjiang Central Hospital of Chongqing from May 2015 to May 2017 were randomly divided into observation group (n =43) and control group (n =43) by random number table method.The control group was treated with microsurgical clipping,while the observation group was treated with intravascular interventional embolization.The therapeutic effect,neurological function recovery,postoperative complications and prognosis of the two groups were compared.Results The operation time,intraoperative blood loss,postoperative respiratory recovery time and postoperative extubation time of the observation group were significantly less than those of the control group (P ＜ 0.05);the complete recovery of the observation group was significantly higher than that of the control group,and no recovery was significantly lower than that of the control group (P ＜ 0.05);the incidence of complications in the observation group was significantly lower than that in the control group (P ＜ 0.05);the proportion of 5 points in the observation group was significantly higher than that in the control group (P ＜ 0.05).Conclusions Intravascular interventional embolization in the treatment of posterior communicating aneurysm combined with oculomotor paralyses can promote the recovery of nerve function,reduce the incidence of postoperative complications,have a good prognosis and a definite effect,which can be used as the first choice of treatment.

Residual lesions in patients undergoing microsurgical clipping of cerebral aneurysms in a reference university hospital

OBJECTIVES: This study aimed to analyze the incidence and epidemiological, angiographic, and surgical aspects associated with incomplete clipping of brain aneurysms in a cohort of patients undergoing microsurgical treatment. METHODS: The medical record data of patients who underwent microsurgery for cerebral aneurysm treatment and postoperative digital subtraction angiography, treated at the same teaching hospital between 2014 and 2019, were retrospectively analyzed. The studied variables involved epidemiological and clinical data, as well as neurological status and findings on neuroimaging. The time elapsed between hemorrhage and microsurgical treatment, data on the neurosurgical procedure employed for aneurysm occlusion, and factors associated with the treated aneurysm, specifically location and size, were also evaluated. RESULTS: One hundred and seventeen patients were submitted to 139 neurosurgical procedures, in which 167 aneurysms were clipped. The overall rate of residual injury was 23%. Smoking (odds ratio [OR]: 3.38, 95% confidence interval [CI95%]: 1.372-8.300, p=0.008), lesion size >10 mm (OR: 5.136, CI95%: 2.240-11.779, p<0.001) and surgery duration >6 h (OR: 8.667, CI95%: 2.713-27.681, p<0.001) were found to significantly impact incomplete aneurysm occlusion in the univariate analyses. CONCLUSION: Incomplete microsurgical aneurysm occlusion is associated with aneurysm size, complexity, and current smoking status. Currently, there is no consensus on postoperative assessment of clipped aneurysms, hindering the correct assessment of treatment outcomes.

Approaches To A-Com Artery Aneurysms: Different Paths For One Goal

BACKGROUND: A-com artery aneurysms are the most common intracranial aneurysms. Clipping and coiling are the two options available for treatment of these aneurysms. Microsurgical clipping, although invasive, is more suitable for the economically challenged sector of our society. AIM:To evaluate the mortality and morbidity of clipping A-com artery aneurysms by different surgical approaches.Settings and Design: This is a non-randomized prospective multiple centre study. MATERIALS AND METHODS:Patients with A-com artery aneurysm fullling the inclusion criteria and managed with microsurgical clipping were included in the study. Patients were evaluated preoperatively and postoperatively with CT Scan Brain (Plain), 3D- CT Angiogram of Brain or Digital substraction Angiography of Brain.STATISTICAL ANALYSIS:Data collection and analysis, was performed using the statistical package for the social sciences version 16 (SPSS, INC, Chicago, IL). RESULTS:A total of 34 patients of A-com aneurysms (non-giant) were included in the study. Male: Female ratio of 1.62:1 with male preponderance. All the aneurysms were microsurgically clipped by either Pterional transsylvian or modied gyrus rectus or interhemispheric approach. The mortality and morbidity in different surgical approaches were analyzed. CONCLUSION:Mortality depends on the preoperative grade of subarachnoid hemorrhage. Type of surgical approach has no relation to mortality or morbidity.

Foraminotomía optica para el clipado de aneurisma carótido-oftálmico superior / Optical foraminotomy for clipping of superior carotid-ophthalmic aneurysm

Introducción: Los aneurismas carótido-oftálmicos generalmente causan problemas visuales, y su tratamiento quirúrgico sigue siendo un reto debido al objetivo de preservar y/o mejorar la función visual. Descripción del caso: Presentamos caso de intervención quirúrgica de aneurisma carotídeo-oftálmico superior. Masculino de 64 años de edad con déficit de campo visual inferior izquierdo y cefalea. La reconstrucción angio-TC mostró un aneurisma carotídeo-oftálmico superior izquierdo no roto (4x5 mm). Paciente colocado en posición supina, con la cabeza fija en cabezal Sugita de 4 puntos, con una rotación de 15° hacia el lado contralateral. Una craneotomía pterional clásica con fresado del ala esfenoidal, con apertura de la fisura silviana y carotidea se realizaron bajo el microscopio. Se realiza una incisión dural circunferencial sobre el canal óptico. El techo óseo del canal óptico, así como sus paredes medial y lateral, se eliminan cuidadosamente con una fresa diamantada de 3mm con drill de alta velocidad con irrigación constante para evitar daños térmicos sobre el nervio óptico. El nervio óptico con un disector de Penfield N° 7 se eleva suavemente, lejos de la arteria carótida, para facilitar la exposición del cuello aneurismático para el clipado. Resultados: La apertura extensa del canal óptico y la vaina del nervio óptico se logró con éxito en el paciente, lo que permitió un ángulo de trabajo con la arteria carótida para la correcta visualización del aneurisma. Se logró el correcto clipado en el control de AngioCT postoperatoria. Conclusión: La foraminotomía óptica es una técnica fácil y recomendada para exponer y tratar aneurismas carotídeos-oftálmicos superiores y, además, permitir la descompresión del nervio óptico.

Introduction: Carotid-ophthalmic aneurysms usually cause visual problems, and its surgical treatment remains challenging due to the goal of preserving and/or improving the visual outcome. Case description: We present a surgical intervention of superior carotid-ophtalmic aneurysm. A 64-year-old man with a left inferior visual field deficit and headache. The angio CT reconstruction showed a left incidental superior carotid-ophthalmic aneurysm (4x5mm). Patient positioned in supine, with the head fixed in a 4 pin Sugita headholder with a 15° rotation to the contralateral side. A pterional craniotomy and flattening of sphenoid ridge with the usual drilling procedure with the opening of the Sylvian fissure to the carotid cistern were done under the microscope. A circumferential dural incision is made above the optic canal. The bony roof of the optic canal as well as its medial and lateral walls are carefully removed with a 3mm diamond high speed drill under constant irrigation to avoid thermal damage to the optic nerve. The optic nerve becomes gently retractable with a N° 7 Penfield dissector to some extent away from the carotid artery, to facilitate the aneurysmal neck exposure for clipping. Results: Extensive opening of the optic canal and optic nerve sheath was successfully achieved in the patient allowing a working angle with the carotid artery for correct visualization of the aneurysm. The correct clipping was observed in the postoperative AngioCT control. Conclusion: Optic foraminotomy is an easy and recommended technique for exposing and treating superior carotid-ophthalmic aneurysms and moreover allowing optic nerve decompression.

Clinical research in the endoscopic management of digestive fistula / 中华消化内镜杂志

Objective To evaluate the therapeutic value of endoscopic jejunal tube placement, endoscopic clipping, and over the scope clip ( OTSC) for digestive fistula. Methods Data of 38 patients with digestive fistulas at the First Affiliated Hospital of Soochow University admitted from July 2015 to July 2017 were retrospectively analyzed. Treatments were chosen according to the size and the site of the fistulas. Thirteen patients underwent jejunal tube placement ( the jejunal tube group ) , 20 underwent endoscopic clipping( the endoscopic clipping group) , and 5 underwent OTSC( the OTSC group) . The technical success rate, clinical cure rate and postoperative hospital stay were analyzed. Results All patients received the endoscopic operation successfully with no significant complications. In the jejunal tube group, 4 patients′fistulas fully healed, lesion was smaller after treatment in 3 patients, lesion didn′t change in 5 patients, and 1 patient died. The complete cure rate was 30. 8％ (4/13), and the postoperative hospital stay was 47. 4± 14. 1 days. For the endoscopic clipping group, 16 patients′ fistulas fully healed, lesion was no smaller compared with that before treatment in 3 cases, and 1 patient died. The complete cure rate was 80. 0％ ( 16/20) , and the postoperative hospital stay was 17. 9 ± 8. 9 days. Total patients in the OTSC group were completely cured, with 100. 0％( 5/5) of complete cure rate. One patient with refractory esophageal fistula underwent OTSC repeatedly with endoscopic clipping, and the healing time of fistula was 102 days. The postoperative hospital stay of 4 others was 5. 3±1. 7 days. The cure rate of fistula was higher (P=0. 03, P<0. 001) and the postoperative hospital stay was shorter ( P=0. 04, P<0. 001) in the OTSC group compared with the clipping group and the jejunal tube group. Conclusion Endoscopic management is safe and effective for digestive fistulas with less trauma, easy performance and short time of healing.

Methods The clinical data of 21 patients with lower ureteral stricture undergoing laparoscopic ureterobladder reimplantation from Mar. 2014 to Mar. 2016 were retrospectively analyzed. Twelve patients receiving conventional laparoscopic ureterobladder reimplantation were assigned to control group, and 9 patients receiving laparoscopy-assisted external ureterobladder reimplantation were assigned to improvement group. The ureter of the patients in the improvement group was separated under laparoscopy, the narrow ureter was severed, and the proximal ureter was taken out from the 12-mm Trocar. Then, the broken end of ureter was clipped under euthyphoria, and the double J tubes were inserted and fixed on the ureteral mucosa with 4-0 absorbable sutures and then sent back to the pelvis. The bladder was mobilized under laparoscopy, and the bladder and ureter were anastomosed. Results The surgery was successfully completed in all the 21 patients without transferring to open surgery or urine leakage after operation. The operation time was significantly shorter in the improvement group versus the control group ([77±17] min vs [104±20] min, P<0.05). All patients were followed up for at least 6 months after operation. Both ultrasonography and intravenous pyelography showed no ureteral anastomotic stricture. The hydronephrosis was alleviated to some extent. Cystography showed that 2 patients had reflux, with 1 case in each group. Conclusion In laparoscopic ureteral reimplantation, external ureteral clipping and insertion of double J tube are minimally invasive, and can shorten operation time and make the surgery less complex.

The efficacy of microsurgical clipping treatment for intracranial aneurysm rupture and optimal timing research / 中国基层医药

Objective@#To study the clinical efficacy of microsurgical clipping treatment for intracranial aneurysm rupture and optimal timing.@*Methods@#From January 2016 to December 2017, 80 patients with intracranial aneurysm rupture in Taizhou Enze Medical Center(Group) Hospital were randomly divided into the control group (24-72h after rupture) and the observation group (within 24h after rupture) according to the digital table, with 40 patients in each group.The pre- and intra-surgical re-rupture and surgical clipping, post-surgical complications, and clinical efficacy of 6-month follow-up in the two groups were observed and compared.@*Results@#Compared with the control group, the incidence rate of pre-surgical re-rupture was significantly reduced in the observation group (0.0% vs.10.0%, χ2=4.21, P<0.05). Compared with the control group, the incidence rate of post-surgical complications was obviously reduced in the observation group (20.0% vs.42.5%, χ2=4.71, P<0.05). Compared with the control group, the excellent rate of treatment was significantly improved in the observation group (87.5% vs.65.0%, χ2=5.59, P<0.05).@*Conclusion@#The microsurgical clipping treatment can improve the clinical efficacy of intracranial aneurysm rupture and sooner surgery with better prognosis.

Analysis of balloon-assisted occlusion technique in hybrid operation of paraclinoid aneurysms of internal carotid artery / 中国脑血管病杂志

Objective To evaluate the safety and effectiveness of balloon-assisted clipping of paraclinoid aneurysms with hybrid operatioa Methods From July 2011 to July 2018,119 consecutive patients treated with the balloon-assisted clipping of paraclinoid aneurysms at the Hybrid Operation Room, Department of Neurosurgery, West China Hospital,Sichuan University were enrolled retrospectively. Patients' age, gender, Hunt-Hess grade, ocular symptoms at admission, and location and size of aneurysms were collected. Balloon-assisted craniotomy for clipping aneurysms was used ,95 of them were treated with detachable balloon at the proximal end of the aneurysms, and 24 were blocked by balloons in the aneurysm neck straddles. During the operation,the state of discharge after surgery,and the follow-up results at 6 months after discharge of the patients were observed. The operation effect and complications were evaluated.Results Of the 119 patients,94 were female and 25 were male;aged 27 -82 years (mean 57 ± 15 years). Twenty-nine patients (24. 4%) showed decreased vision,62 (52. 1%) had dizziness and headache symptoms. The remaining 28 had no obvious symptoms. Hunt-Hess grade III in 3 cases (2. 5%) ,grade I-II in 42 cases (35. 3%) ,the remaining 74 (62. 2%) were unruptured aneurysms. Twenty-one patients (17.6%) had clinoid segment aneurysms, 82 (68.9%) had ophthalmic segment aneurysms, and 16 (13. 4%) had posterior communication aneurysms. The maximum diameter of the aneurysms was 5 to 35 mm (mean 19 ±7 mm) ,and the aneurysm diameter of 112 patients (94.1%) were > 10 mm. The aneurysms were successfully clipped in 111 cases (93. 3%) during the operation. Five patients had aneurysm neck and internal carotid artery lacerations during the clipping,and one was obviously unable to be clipped due to the neck calcification. After Hyperglide balloon saddle block, 1 patient occurred balloon rupture during the puncture and aspiration of the aneurysmal cavity. When the balloon was blocked in 1 case, balloon displacement occurred during repeated filling adjustment of aneurysm clips and the distal end detached into an aneurysm cavity and was clipped by an aneurysm clip. Three patients died at discharge, they were all aneurysm neck and internal carotid artery lacerations, and they were patients with massive cerebral infarction after aneurysm tapping. Five patients were in a coma; another 6 had hemiplegia symptoms. The remaining 105 patients (88. 2%) had no obvious neurological deficits at discharge. Six months after discharge, 11 patients with neurological deficits were followed up by telephone. Among the 5 comatose patients,3 died within one week after discharge. The consciousness of 2 cases changed from coma to indifference, their left limb muscle strength was grade III,and blurred vision was the same as before operation. Of the 6 hemiplegic patients, 1 died 3 months after discharge, and the other 5 had clear consciousness and their blurred vision was the same as before operation, all had limb hemiplegia, and their muscle strength was grade I - U - Conclusion Hybrid surgery with balloon-assisted clipping technique may effectively treat complex paraclinoid aneurysms.

Effect analysis of microsurgical clipping treatment of middle cerebral aneurysms / 中国脑血管病杂志

Objective To investigate the safety and effectiveness of microsurgical clipping for the treatment of middle cerebral artery aneurysms (MCAA). Methods From May 2008 to May 2018,the clinical and imaging data of 241 consecutive patients with MCAA (258 aneurysms) treated with microsurgical clipping at the Department of Neurosurgery,General Hospital of Eastern War Zone were analyzed retrospectively, including 160 patients ( 172 aneurysms) with ruptured aneurysm (ruptured group) and 81 patients (86aneurysms) with unruptured aneurysm (unruptured group). Aneurysm clipping or aneurysm clipping + hematoma evacuation was used via ptcrion approach. The Glasgow coma scale ( GCS) score was used to evaluate the state of consciousness before and after surgery in patients of the ruptured group. The clinical and imaging follow-ups (CT angiography [ CTA ] or DSA ) were performed regularly after procedure. SPSS 20. 0 statistical software was used to analyze and process the data. Results All the aneurysms were completely clipped during the operation in both groups. Of the 160patients in the ruptured group,the preoperative GCS score was 8 ±2,9 had cerebral infarction in the blood supply area of middle cerebral artery branches after operation,3 had hydrocephalus after operation, and 2 had unexplained cerebral hemorrhage after operation. The incidence of postoperative complications was 8. 8% ( 14/160). No aneurysm was found on CT angiography or DSA after procedure. Postoperative GCS score 9±3 at 15±2d was improved compared with the preoperative CCS score (< = -6. 240, P <0. 01). Seventy-eight patients were followed up without aneurysm recurrence. Of the 81 patients in the unruptured group,7 (8.6%) had cerebral infarction in the blood supply area of middle ccrcbral artery branches after operation. No aneurysms recurrence was found on CTA or DSA after operation, and 45 patients were followed up without aneurysm recurrence. There was no significant difference in the incidence of postoperative complications between the two groups (x∗ =3.280, 0. 194). Conclusion Microsurgery clipping is a safe and effective method for MCAA,and it is very important to improve the conscious state in patients with aneurysm rupture.
